In this year’s version of the Dell G7 17 7700, there have been a lot of changes and improvements made by Dell since the previous version did not do well. Besides the much better design, the manufacturer has also made a lot of internal improvements to the laptop. In the next few lines, we are going to look at one of the strongest updates that the company made – the display.
The Dell G7 7700 has a 17.3″ (43.94 cm) display with a resolution of 1920×1080. The panel has a refresh rate of 144Hz, the screen ratio is 16:9 and the pixes density is 127 ppi. The refresh rate of 144Hz is a selling point for gamers as the high refresh rate is beneficial for multiplayer games like CS:GO. The screen turns into Retina when viewed at distance equal to or greater than 69cm (27″) (from this distance one’s eye stops differentiating the separate pixels, and it is normal for looking at a laptop).
The viewing angles of the display are good and the average brightness of the whole screen is 332 nits. The Correlated Color Temperature on a white screen is 6500K – matching the optimal for the sRGB standard of 6500K.
Values of dE2000 over 4.0 should not occur, and this parameter is one of the first you should check if you intend to use the laptop for color-sensitive work. The contrast ratio is good – 1320:1.
The yellow dotted line shows Dell G7 17 7700’s color gamut coverage.
Its display covers only 90% of the sRGB/ITU-R BT.709 (web/HDTV standard) in CIE1976.
Below you can compare the scores of Dell G7 17 7700 with the default settings (left), and with the “Gaming and Web design” profile (right).
As you can see, the Dell G7 17 7700 is doing perfectly for a laptop that has another main purpose.
Response time (Gaming capabilities)
We test the reaction time of the pixels with the usual “black-to-white” and “white-to-black” method from 10% to 90% and vice versa.
We recorded Fall Time + Rise Time = 10 ms.
Blue light emissions
Installing our Health-Guard profile not only eliminates PWM but also reduces the harmful Blue Light emissions while keeping the colors of the screen perceptually accurate. If you’re not familiar with the Blue light, the TL;DR version is – emissions that negatively affect your eyes, skin, and your whole body. You can find more information about that in our dedicated article on Blue Light.

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.
Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.
Design and Gaming
This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.
THealth-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.
All in all, the Dell G7 17 7700 has a really good all-round display. The display is color accurate and has a refresh rate of 144Hz. Furthermore, the laptop has impressive specs and boasts a very good battery life. Overall, if you want a device that is not only good for gaming but also for color-sensitive work or you are a fan of fast displays and would like to get a 144Hz display with quick pixel response times – this is the laptop for you. Dell has done a really commendable job with this year’s version of the Dell G7 17 7700.
